Besides the fact that it is oldamundo it was really hard. There were timed missions and things. I hate timed missions.
This game remains a pretty good game- nothing compared to Halo and the like- but still pretty fun. All I can really remember about this game is that you got to destroy stuff by smashing it with the robot or crashing into it with a car. That was the real objective of the whole game-to destroy stuff. If you still have an N64 you should try this game. Could probably get it pretty cheap, too.
